The Formatt Combination 85B/Neutral Density Glass Filter is a very unique filter that offers possibilities that other filters don't.

Neutral Density FilterNeutral Density filters have several uses and offer the possibility to achieve otherwise unachievable results. ND filters appear grey and reduce the amount of light reaching the film. They have no effect on color balance.

Often it is necessary or desirable to balance the light intensity in one part of a scene with another. This is especially true in situations where you don't have total light control, as in bright contrasty landscapes. Exposing for the foreground will produce a washed-out, over-exposed sky while exposing for the sky will leave the foreground dark and under-exposed. This filter enables cloud detail to be kept correctly exposed in the picture.

Determining which graduated neutral density filter yields ideal results for any given lighting situation takes knowledge, experience and a collection of such filters. Choose the filter strength which adjusts the lighting to stay within the exposure latitude (greatest difference between bright/dark values) which still shows details in both of the digital or film medium in use.

Speaking generally, the 2-stop value (ND 0.6 - the filter's clear portion allows 4x more light to pass vs. darkest portion) effectively compensates average bright sky-to-foreground situations, and the soft transition is applicable more often to a scene than the hard transition

85B Color Conversion FilterAn 85B filter will produce natural colors when shooting with tungsten film outdoors. What do you do when you must take some photos outdoors and all you have left is tungsten film? Using tungsten film in daylight will produce a bluish cast in the photograph.

The 85 series of filters will "bring back", i.e. color balance the tones in your images. These yellow filters are used to correct differences in color temperature between the recording medium (film/video) and the light source.

Note: Whereas the 85 series is used for tungsten film under daylight conditions, use the 80 series of filters when using daylight film under tungsten lighting

85 Series Color Conversion Chart

An 85 decreases the color temperature from 5500-3400 Kelvin

An 85A decreases the color temperature from 5500-3100 Kelvin

An 85B decreases the color temperature from 5500-3200 Kelvin

An 85C decreases the color temperature from 5500-3800 Kelvin

Neutral Density Filters Have Four Main Uses

To enable slow shutter speeds to be used, especially with high speed films, to record movement in subjects such as waterfalls, clouds, or cars

To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background

To decrease the effective ISO of high speed film (above ISO 400) and allow it to be used outdoors in bright situations

To allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which could cause overexposure
